The Biemmedue EK S 20 air heater is a device used for heating environments using electrical energy . This versatile device can be installed on both walls and ceilings and is equipped with integrated resistors and an internal fan . It is ideal for heating large areas such as warehouses, gyms, sports facilities and livestock farms, ensuring power and efficiency to meet professional needs.
Thanks to the high-performance three-phase fan and the advanced heat exchange system, the Biemmedue EK S 20 fan heater ensures rapid and uniform heating . The robust structure and quality components are designed to withstand intensive use , maintaining constant performance over time. Furthermore, this model offers an intuitive interface, with additional features such as a 3 m cable remote control and a cutting-edge safety system , for practical and safe use.

Biemmedue EK S 20 has a max. nominal thermal power of 20 kW with a 100% efficiency, managing to guarantee an air flow rate of 2300 m²/h. With a three-phase 400 V electrical power supply, this fan heater is extremely silent, reaching just 65 db(A) at 1 meter away.
Biemmedue EK S 20 is equipped with electric resistors that heat the air sucked in from the environment . The fan heater takes the cold air, conveys it through the resistors, where it is heated, and reintroduces it into the environment, ensuring continuous circulation of hot air for uniform and efficient heating.
This professional electric heating system is highly appreciated for its efficiency and ease of installation , especially in environments where it is not possible to use other heating systems such as commercial, industrial and even domestic premises.
The unit is equipped with particularly quiet three-phase fans, which ensure even heat distribution without annoying noises.
The finned resistors, made of AISI 321 stainless steel, improve heat exchange, optimizing energy efficiency and the life of the appliance. The external casing of Biemmedue EK S is instead made of painted steel sheet.
The room thermostat socket allows you to precisely adjust the desired temperature, ensuring comfort and energy savings. The practical remote control with 3 m cable allows you to control the unit from a distance, improving practicality and ease of use.
The power selector allows you to adapt the operation of the fan heater to the specific needs of the room, maximising efficiency.
Equipped with a manual reset safety thermostat and a post-ventilation thermostat , this model ensures maximum safety during operation and cooling of the unit.
The Biemmedue EK S Electric Heater is supplied with ceiling or wall installation brackets to allow for easy use depending on the area to be heated. Furthermore, its fins are adjustable, allowing the air flow to be directed where necessary.


Biemmedue EK S Aerotermi electric heaters do not produce smoke, harmful gases or vapours which can be dangerous to your health or cause safety risks caused by open flames or gas leaks. Furthermore, Biemmedue air heaters are much easier to install and do not require masonry work or the laying of pipes for the transport of fuels or connections to boilers.
Another advantage is the greater control of temperature and heat distribution , allowing you to easily adjust the desired temperature according to your preferences and the characteristics of the area to be heated.
Finally, energy efficiency and lower environmental impact also play in favour of the Biemmedue EK S Air Heater, which in fact has a lower impact than traditional fossil fuel heating systems.
